T (0 whom it may concern:

Be it known that 1, PAUL HAHN, engineer, a subject of the King Germany, residing at Niederlahnstein, Rhine Province, Germany,have invented certain new and useful Improvements in Machines for Mercerizing Yarn in the Form of Skeins, of which the following is a full, clear, and exact description.

The present invention relates to a machine for mercerizing yarn in the form of skeins; and its essential features are chiefly that all the diflerent working processes necessary for the mercerizing processas, for instance, the stretching and releasing of the yarn, the opening and shutting of the inlet and outlet valves for the lye and the rinsing water, and also the wringing out of these fluids from the skeins is done automatically by the rotation of a number of eccentrics and cam-disks fixed to a common axle, which for their part work on lever mechanisms acted upon by weights or springs. By uniting these eccentrics and cam-disks on a common axle the whole working of the machine is centralized, whereby not only great simplicity and sureness in working, but also a stout and short construction are warranted, and it is easy to have a full View of the machine.

The annexed drawings show an example of this invention.

Figure 1 is a side View, Fig. 2 is a front view, and Fig. 3 a top or plane view, of the machine. A vertical plane through the middle of Fig. 3 divides the same in two equal parts-that is to say, exactly the same mechanisms will be found on the right side as on the left side. The characters of reference are therefore the same on the left as on the right hand side, with the exception that the leftside parts have the index (4.

Around the shaft 3 as stationary fulcrum an unequal-armed bent lever 1 2 (1 2) is ar ranged, whose longer arm bears a weight 9, (9,) consisting of disks and capable of being regulated by adding or removing disks, while the shorter arm 2 by means of links 4: (Q) is connected with the bearings of the fluted tension-cylinder 5, (5,) said bearings gliding in guides in such a manner that the cylinder may of Prussia, Emperor of (N0 model.)

be approached to or removed from the fixed cylinder 7 (7) by turning the bent-lever arm 1 2, (1 2,) which is to say that the skein 6 (6) around 5 (5) and 7 (7) may be tightened or loosened. The turning of the bent-lever arm 1 2 (1 2) is effected by means of the twoarmed lever 10 11 (10 11) turning around the shaft 12 and provided at its ends with rollers 13 1 1, (13 1,) the roller 13 lying in the rotation plan of a curved or eccentric disk 16 (16) turning around the common axle 17 .7 When in the course of the rotation the obliquely-ascending part of the eccentric 16 (16) reaches the roller 13, (13,) Fig. 2, the same is pressed to the left, and the lever 10 (10) and the roller 14: (1 1) effects by its pressure against the block 15 of the lever-arm 2 (2) a turning of the same to the right, which is equivalent to a raising of the. weight 9 (9) and loosening of the skein 6 (6) in nearing the cylinder 5 (5) to cylinder 7, (7 7). SO that the yarn can now be taken OE and a new skein laid on both cylinders. After this influence by the weight 9 (9) a gradual return motion of the leverarms 1 2 (1 2) and 10 11 (10 11) takes place during the further rotation of the eccentric 16, (16,) because now the part of the eccentric with the smaller diameter can move freely past the roller 13 (13) Without touching the same. Vhen the tightening of the yarn has begun by the roller 13 (13) sliding down from the highest points of the eccentric 16,(16,-) the impregnation of the skein 6 (6) with lye is effected by the automatic opening of a valve 39, common to both sides of the machine, which forms the stop appliance of a lye-conducting pipe, (not shown,) the lye in said pipe being under pressure, and thereby entering into a pipe 10 when the valve 39 is opened. Said pipe 10 leads to a horizontal pipe 2 1, which leads into tanks 18, (18.) The opening of the lye-valve 39 is eifected by the disk turning on the axle 17, and provided with the cam 32; further, by the two-armed lever 3&,carry ing at its end the roller 35, and by the link 36, connected with a lever turning on 11, the left arm of which is indicated as 4:3 and the right arm as 37 .7 Said lever is regulated by a weight 38 and by a pin connected With the spindle of the valve 39. When the cam 32 during the turning of 3O hits the roller 35 and lifts it, the left part of the weight-lever arm 43 is drawn down around its turningpoint 41, while the right lever-arm 37. with the weight 38, is lifted, which is also the spindle of the valve 39, connected with the leverarm, 37 by a pin. hen the spindle is thus lifted, the lye, which stands under pressure and is introduced into 39 by a pipe, (not shown,-) flows through the pipe 40 into the spirt-tube 24*, which connects both tanks 18, (18%) and is provided with small openings toward the yarn, and the skein, which moves inside the tanks from left to right, is syringed with lye. Simultaneously with the opening of the lye-inlet valve 39 also a movement of the rubber cylinders 8, (8,) directed by the lever-arms 28, (28,) takes place toward the yarn-cylinders 7 (7 as the rollers 33, (33 held up till now by the eccentric bosses 31 (31) of the disks (30 and fixed to the horizontal parts of the bent lever-arms 28, (28%) swinging round the common axle 44, now slide down from the bosses and turn under the influence of the weight 29 downward around the axle 44, whereby the wringing-cylinders 8 (8) are pressed to the circumference of the tension-cylinders '7, (7,) so that the lye is pressed through the core of the yarn, the waste flowing back to the tanks 18, (18?) During the further rotation of the right-side disk 30 around the axle 17 the automatical shutting of the lye-valve 39 is effected by the weight 38", when the roller glides from the cam 32. Now the lye in the tanks must be let out, which is attained by means of two outlet-valves 19, (19",) arranged to the tanks 18, (18.) Together there are four outletvalvestwo, viz., 19 19, on the left and two, viZ., 19. 19*" on the right hand side. The valves 19 19*" are for the outlet of the lye, and the valves 19 19 for the outlet of the rinsingwater. The two outlet-valves on the same side are put in action by a single cam-disk 25, (25,) provided with two cams 26 27, (26 2P.)

hen during the turning ofthe axle 17 the cams 27 (27) of the disks 25 (25) lift the rollers 22,(22,) the lye-valve 19 (19) of each tank 18 (18) is opened by means of the leverarms 21 (21) and the spindles 20,(20 provided with the weights 23,(23,) and the lye flows through the pipe 42' (42) into the tank 45. The cam 27 (27) having passed the roller 22',(22',) the weight 23 (23) drops the valverod 20 (20) and shuts the valve 19. On the left-hand side the cam 32 of the disk 30 now comes in contact with the roller 25 of the lever 34 and by means 'of the lever connection 36 37 a working process similar to that of the lye-valve 39 'on the right-hand side takes place; it is to say,the water-inlet valve 39 is opened by the lifting of the spindle, which results in the flowing of the rinsing-water into the pipes 40 24 and the filling of both tanks with said water. The rinsing-water syringes the yarn by means of the syringe arrangement of the pipe 24. 1V hen the yarn is thus well rinsed and the waste has been wrung out by the wringing device 8 (8*) in the same manner as by the lye, the disk 25 (25) comes in action,as this time the cam 26 (26) of said disk moves past the roller 22 of the lever 21, (21,) raises the latter, and thus opens the water-outlet 19, (19,)so that now the water can run out from the tanks 18 (18) through the pipe 42 42. Now the lever 10 11 comes again into action by running down from the boss of the eccentric l6,(16,) the skein 6 (6) is loosened and can be removed and substituted by a new one, the treatment of which is effected in the very same manner.
